Plesk for Linux kb: technical

Applicable to:

  • Plesk for Linux

Symptoms

  • Plesk migrator is unable to connect with source AWS Linux server with the following message:

    CONFIG_TEXT: Please login as the user “centos” rather than the user “root”

Cause

Root login over ssh is not permitted on the source server.

Resolution

  1. Connect to the server via SSH.

  2. Change user to root:

    # sudo -s

  1. Backup /root/.ssh/authorized_keys file:

    # cp /root/.ssh/authorized_keys /root/.ssh/authorized_keys_backedup

  1. Open file /root/.ssh/authorized_keys in a text editor, in this example we're using vi editor.

    # vi /root/.ssh/authorized_keys

  2. Delete all text before "ssh rsa" and save the file.

  3. Open file /etc/ssh/sshd_config in a text editor.

    # vi /etc/ssh/sshd_config

  4. Set 'PermitRootLogin' and 'PasswordAuthentication' parameters to 'yes'.

    # cat /etc/ssh/sshd_config | egrep "PasswordAuthentication|PermitRootLogin"
    PasswordAuthentication yes
    PermitRootLogin yes

  5. Restart SSHD service:

    # systemctl restart sshd.service

  6. Redo the migration.

    Actually, to make everything clear:

    Steps 1,2,3,4,5 are correct, but after step 6 you should also check that PasswordAuthentication is also set to yes, otherwise it will not work.
